Fix:
String selectSQL = "SELECT<seq2seq4repair_space>sum(price)<seq2seq4repair_space>AS<seq2seq4repair_space>price<seq2seq4repair_space>FROM<seq2seq4repair_space>ingredient<seq2seq4repair_space>NATURAL<seq2seq4repair_space>JOIN<seq2seq4repair_space>menu_ingredient<seq2seq4repair_space>WHERE<seq2seq4repair_space>menu_id<seq2seq4repair_space>=<seq2seq4repair_space>?" ;
